Thank you! And all the best!

Hi Alpay, Thank you for your patience, the quality assurance team have got back to me and they say that the vias are tented but the solder mask is just a little thin. This is within IPC-class 2 standards however and about 30% of boards will come out like this. For BGA via tenting, they suggest solde...

Thank you Alpay, these photos are much clearer but they raise some other questions. The difference between the two photos is obvious but you can also see the edge of the BGA pad opening between the via and pad. I have forwarded the case to the quality assurance engineers for a second opinion and the...

Hello Alpay, Thank you for letting us know. I have checked our support system and it seems we haven't received any e-mails from you to our general support since the 2nd of November, which was regarding another issue. Could you PM me the e-mail address you sent them to? Also, regarding your problem w...

Hello youngc1! Sorry, but I am afraid we don't have this option at the moment.

To have (plated) through holes (copper pads on both top and bottom layers) you would need double layer ...

Hello Pierre, I've checked the e-mail accounts and we didn't e-mails saying the messages were being blocked so that is strange, I have sent you a message including the PCB manufacturing files we have on record to both e-mail addresses, there are 13 files included in total. Let me know if they have b...

Hello Pierre, We are sorry to hear of your of troubles with the service, but I have checked our support system and customer support responded to your messages on the 23rd, 24th, and 25th (GMT+8). Could you check your spam folders? Maybe it got lost in there. It seems there are two solder mask layers...
